Abstract (en)

[origin: WO9913662A1] In a model of a wireless communication system service area (160), a set of characteristics associated with the reception of a model signal (210) are calculated (308), preferably using ray-tracing techniques, wherein the model signal (172) is transmitted from a selected location (162) to a receiver location (166). Next, a set of characteristics that describe a received signal at a receiver location in the wireless communication system service area are measured (316), wherein the receiver location corresponds to the receiver location in the model (160). Thereafter, a relationship between the calculated set of characteristics and the measured set of characteristics is determined (318), and the location of the subscriber unit that transmitted the received signal is estimated (320) in response to the relationship between the calculated set of characteristics and the measured set of characteristics.
